Example Problem gradient lines and Equal Straight Line and Discussion

Example Problem gradient lines and Equation Straight Line - in a previous article Mathematical Formulas Basic 've never provide a discussion and explanation of Definition Equation Straight Line and How to draw but in the discussions there has been no examples of questions about the straight line equation. Therefore, in this article will be given some examples of questions about Gradient Lines and Straight Line Equation not least, we also provide an explanation on how to resolve such questions. Come on, just in see because as follows:

Sample Questions and Discussion gradient lines and Equation Straight Line


Example Problem 1: [1945901million]
A straight line has the equation Y = -2x + 4. Determine the gradient of the line!

Solved:
Given: PGL -> Y = -2x + 4.
Asked: gradient (m)?

Answer:
y = mx + c, m = gradient = -2
So the gradient of the line is -2

Example Problem 2: [1945901million] Given equation 4x + 2y-5 = 0. Determine the gradient of the line!

Solved: [1945901million]
Given: PGL -> 4x + 2y-5 = 0, A = 4, B = 2
Asked: gradient (m)?

J Awab:




So the gradient of the line is -2


Example Problem 3: [1945901million]
Determine the gradient of the line through the points A (1,2) and point B (-2.3)!

Solved: [1945901million]
Given: A (1.2) x1 = 1, y1 = 2
B (-2.3) x2 = -2, y2 = 3
Asked: gradient (m)

Thread :





J adi gradient of the line is - 1/3

[1945901million]
Example Problem 4: [1945901million]
A line through the center point and the point P (3 , 2). Find the gradient of the line!

Solved: Given: P (3.2) x1 = 3, y1 = 2
The center point O (0,0) x2 = 0, y2 = 0
Asked: gradient (m)?

Answer: [1945901million]

[1945902million]




So the gradient of the line is -2/3


Sample Problem 5: [1945901million]
DRAWINGS A perpendicular to the line that has the equation y = 8x +6. Specify gradient line A!

Solved:
Given: A line perpendicular to the line degan PGL -> y = 8x +6 ..
Asked: gradient (m) ?

Answer:
Two lines perpendicular to each other then the product of the slope is -1, m1 x m2 = -1
m1 = 8
m1 x m2 = -1
8 x m2 = -1
m2 = -1/8

That's some [1945903million] Example Problem Gradients lines and Equations Straight line and Discussion we can give on this occasion. Hopefully we can give examples of questions that more at another opportunity. Thank you for listening to this discussion well, see you again in the discussion of other issues. Goodluck !!

Units of Size The number of Lusin, Gross, Rim, and Kodi

Unit Size The Number of Lusin, Gross, Rim, And Kodi - When carrying out your daily activities you must have heard some terms like Lusin, Gross, Rim, and Kodi in mathematics the term is called a unit of measure of quantity or quantity. This unit is commonly used to express the number of items or objects. For those of you who do not know or have not memorized by the size of the unit, let us study it together by listening to the discussion The Basic Mathematical Formula on the following unit size sums: The most commonly used unit of measure quantities is : 1 dozen = 12 pieces 1 gross = 144 pieces = 12 Lusin 1 score = 20 pieces ] 1 rim = 500 glue Bar The use of units of measure of the number of Lusin, Gross, Rim, and Kodi The above sizes are usually used in accordance with certain types of goods, for example: Lusin The term dozen is more often used to express the number of items such as glasses, plates, spoons, jars, and so on.

Example Problem Arithmetic Social About Discount / Rebate

Example Problem Arithmetic Social About Discount / Rebate - the meaning of rebates are rebates granted to a product or service. We are more familiar with rebates as a discount. You'll often see at the supermarket or supermarket there are a lot of rebates or discounts, it is an example of a rebate. If you are curious about how to calculate the price cuts, the Mathematical Formulas Basic will give his review to you through examples to the following: Example Problem Discussion and Arithmetic Social About Rabat Example Problem 1 Melly want to buy a dress for Rp 120,000. It turned out that the clothes receive a rebate of 20%. What is the size of the rebate? Answer: clothes Price: Rp 120,000 Rabat: 20% x 120,000 = 20/100 x 120,000 = 24,000 Thus, rabatnya amounted Rp.24.000 Example Problem 2 [1945901million] A Shop, gives a 5% discount for every purchase math book. If a math book has a price of Rp. 85,000. what is the price of the book after the discount?...
